Responsibility of Big Data Team is to analyze Workforce data for finding out patterns in various segments. This also involves implementing data pipeline, interacting with Data Scientist and sharing polished data/patterns with concerned stakeholders for converting this insight into product solutions. Roles/Responsibility: • Implemented Survival regression for a healthcare customer. • Implemented a data pipeline for ingesting Workforce data into HDFS. • Implemented a pipeline for calculation of important index for retail customer data. • Performed optimization of multiple Spark jobs. • Participated in design and implementation of a Spark Application for computing weighted volume for healthcare sector. • Participated in a multiple big data POC to evaluate root cause of Overtime for healthcare domain. • Performed visualization of analyzed data using Bokeh library in Zeppelin notebook

The Layer 0 Control Plane allows a customer or management system to easily control the configurable features of a network. It enables a self-aware network that automatically discovers network elements and access points. It allows single ended provisioning with routing, computed by an intelligent path computation engine based on physical and administrative constraints. Flex grid capable Layer 0 Control Plane enable capacity gains by operating on a flexible spectrum, allocating minimum required bandwidth, for a given channel configuration. Roles/Responsibility: • Design and Implementation of Flex grid architecture in Layer 0 control plane. Implemented mechanism for management of media channel and network media channel in control plane. This implementation also facilitates scale up and scale down of optical services. • Design and implemented clustering of alarm using k-mean algorithm, based on various factor. • Participated in design and development of resource adapters of various Ciena devices. • Implementation of acquiring control of legacy services using Layer0 Control plane. In optical network, there are services which are responsible for huge data flow, but these services are being managed manually. Layer0 control plane will provide mechanism for taking ownership of these legacy user services so that these legacy services along with their CRS could be managed in intelligent way. • Implementation of Regen cross connects for optical signal regeneration in R10.2. Based on data traffic condition in network, regeneration of optical data signal might be required for minimization of errors in long haul networks. • Design, implementation and testing of NvDtl feature. This feature provides a mechanism for exclusion of a path or set of paths from service setup. This set of paths is also excluded during any service operation. • Provided active support to PV testing team in multiple release. Resolved multiple complex issue which came during PV testing

Roles /Responsibility:

• Prime contact for Module owner for High Availability module “ispd”, call replication, hit-less upgrade and switchover functionality of SBC. • Designed /implemented multiple features like Path header, Service route RFC and Access-Redirect for Registration, media-call CDR generation. • Delivered enhancement of multiple existing functionalities of the SBC. • Resolved multiple issues related to signaling, memory corruption, memory leaks, race condition, deadlock, replication which came from live deployment of SBC. • Developed a tool using Python for analyzing SBC logs.

Project: Application server, an entity in IMS network, is responsible for providing various VoIP services (call related services as well non-call-related services) to Sip intelligent as well as Sip unintelligent subscribers. Application server fetches service data for a subscriber from HSS using Sh interface. This service data is used in providing multimedia services to a subscriber. Responsibilities: • Implemented and tested out Multithread XML library using Expat XML parser for parsing Service data, received from HSS. • Implementation of service provisioning framework in Application server. • Developed and performed integration testing of SIM module for interacting with HSS. • Carried out debugging and profiling activity for improving performance of the product.
